While sitting at a light my truck jerked really hard once, but ran perfect afterwards. A few days later while driving down the highway it kinda cut out again the same way and died. I haven’t been able to get it started since. The computer showed a malfunction in the ignition coil. They used a test coil and it fired up. After putting a new one in, it wouldn’t start. They tried the test coil again and it still wouldn’t start. Any ideas?
